looks like a pita carrying plants back and forth, i like the auto darkening greenhouse idea, something like a welders mask that changed the color for clear to dark with a elecrical current.
would be pretty awesome!
or just grow autoflowers

thanks for the thread BC, like you said, this is one of the best kept cannabis farmers secrets out there........

my 12' x 25' will be here and set up by april 1st, just in time for my first light dep, april/may....then a may/june, june/july, a short season with no cover aug/sept, and one last light dep, sept/oct........

besides the light deps and short season, there will be a full season, may/oct.........that is a potential six crops in one year........

main concerns are the cold temps here, especially in april and sept , could get really nasty with lots of snow, i am debating on using natural gas (cheapest), propane, or electric heat for those cold april nights........

i am also exploring the idea of using black 55 gallon plastic drums filled with water for some passive solar heat and have access to a small solar panel which could run a small heater.........

otherwise, the really hard part is pulling the tarp over the gh when the wind is blowing 40-60 mph......

ok, so the tricky part is picking the right genetics for your particular needs, vegging them up to the proper size (its all about timing and prep work), and hardening off the plants before they go outdoors...........

hopefully i will be able to pop in from time to time with some pics and updates......

I am just finishing up 2 ladies in mid summer down here in SA. They are in pots and I carry them inside everynight and put them in a cupboard at around 6. I then take them back out at 6 in the morning, or maybe a little later. I am in week 7 at the moment and harvest time is any day now. I figure I could flower more if I bring 2 in 12 hours after sunrise and take them back out after sunset. Then bring 2 more in and take them out 12 hours later. So if it gets light at 4am, bring 2 in at 3:45pm to be safe. Say its dark at 7pm, take first 2 out at 7:15pm and bring 2 more in. Take them out after 7:15am. And repeat for up to 8 weeks or more depending...rain covers are a necessity if you have a wet summer and make sure your indoor cupboard is ventilated at least a bit. It is easier to manipulate a plant in winter where you simply need to break the 12 hours of darkness, wait till an hour or so after the sun goes down and shine a bright torch on any of your ladies that you want to veg longer in winter. Keep the light on for at least a minute, I usually go for about five. You could also have an indoor setup and supplement the extra dayligt hours which would only lead to more yield.Where I stay in sa the only bad time to have flowering bud outside is in summer. Like I said, it is the wet season and is humid as hell, bud rot can become a problem if the big nugs get soaked and aren't thoroughly dried. Anyway, I know this is an old thread but I love this technique of harvesting bud mid summer using the power of the sun.
Peace

Isn't this something you do to cause a plant to hermi? Usually there is a small light that is placed next to the plant to extend the daylight hours, never heard of just shining a light on them for a few minutes.

Brewtxtea, you're right--it's not light-proof. Last year, another flower-forcer told me that he uses one of those white canvas carport things to "bring on the night" for his plants. Even though it's opaque and not even close to light-proof, the plants inside still interpret the dimmer conditions as the onset of night. So this year, instead of constructing another blackout structure, I decided to just use a simple tent and it worked perfectly."

Right on I'll check that out. Yea I basically broke all the rules learning FF this year and they still flowered just fine. Best tip I got was that the plant just has to be covered some way so that most of the light is blocked it doesn't have to be perfect. And I did open up at night, but not every night and sometimes I would forget to open up in the morning for several hours.

This would be reallly really helpful to me, Im high up in the desert mountains. We dont have a long flowering period due to early frosts. Flowerings typically starts the end of july to early august.

So in July I can shade the plants at the end of the day for a couple of hours and this will force them to flower early? And the plants dont need to be completely covered, I can use some kind of shade cloth?
